CRUSHING AND PULVERIZING MACHINE.

Application filed January 20, 1909, Serial No. 473,286.

To all whom it may concern:

Be it known that I, J osnrrr E. KnNNnoi, a citizen of the United States,residing in the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful Improvements in Crushing andPulverizing Machines, of which the following is a specification.

My improvements relate to crushing and pulverizing mechanism in whichthe lower portion of the gyratory shaft is journaled in a bearing whichis free to adapt itself to the axial inclination of said shaft, as setforth in my concurrent application for Patent No. 387,067, filed August5th, 1907, in which case an eccentric bearing is used,- 2'. c. the borein which the lower portion of the shaft is journaled is formed in thebearing eccentric to the central axial line of rotation of said bearing,and the latter is seated centrally in a rotatable sleeve, whereas in thepresent case the axis of bore in which the lower portion of the shaft isjournaled coincides with the central axis of the hearing, and the latteris seated eccentrically within the rotatable sleeve. In either case theresult is practically the same, in that the bearing is free to adaptitself to the inclination of the longitudinal axis of the gyratoryshaft, and I do not seek to cover herein broadly an axially yieldingjournal eccentric to the center of rotation,the present inventionconsisting in the construction and arrangement of parts herein describedand claimed specifically.

In the accompanying drawings, Figure 1, is a central vertical sectionalelevation of a gyratory crusher embodying my invention; Fig. 2, is ahorizontal section upon line 22Fig. 1; Fig. 3, a view similar to Fig. 2,showing a. modification.

I have herein shown my invention as applied to a gyratory shaftsuspended upon an upper bearing, although this is not material, since mymethod of journaling the lower portion of the gyratory shaft may beresorted to where the gyratory shaft is otherwise supported in ways wellknown in the state of the art.

In the apparatus illustrated in the drawings the general arrangement andoperation of parts is substantially the same as in Specification ofLetters Patent.

others of this type, consisting essentially of a truncated conicalcrushing head a, rigidly secured to the shaft A and gyrated thereby 1nan oppositely inclined concave crushing chamber 1), from the lowerportion of which the reduced material drops into the chute chamber 0, inthe usual manner.

The shaft A is provided with an annular shoulder 1, keyed or otherwiserigidly secured to it,said collar 1, resting upon an annular bearing 2,which in turn rests upon an adjustable support 3 mounted in the upperframe plate (Z. Any desired mechanical expedient may be resorted to inmaking the support 3 adjustable vertically, as by forming it with aperipheral male screw thread for engagement with a female screw threadon the upper frame plate (Z, or on the sleeve cl, inserted in the latteras shown in the drawings.

The lower portion of the shaft A is journaled in the bore 4 of thebearing 5. The axis of the bearing 5 is coincident with that of its bore4, and peripherally it is preferably of convex form, uniformly curved inthe arc of a circle. It is seated in a corresponding curved concavity 6,in the sleeve 7, to which the driving gear 8 is secured. The seat 6 forthe bearing 5 is formed in the sleeve 7, eccentric to the centralvertical axis of rotation of said sleeve, and the principle involved inthis method of journaling the lower portion of the gyratory shaft A isessentially that of the ball and socket joint, although the changes ininclination of the longitudinal axis of the shaft A are so slight thatit is not necessary in practice to resort to a spherical form of bearingwhich would be objectionable on account of the lateral space that wouldbe required to accommodate it in the rotatable sleeve.

lVhile free to adapt itself in the eccentric seat 6, to the inclinationof the longitudinal axis of the shaft A, the bearing 5 is held againstrotation within and independent of the sleeve 7 by one or more axiallyarranged keys 9, or equivalent expedients, by which the interlocking ofsaid bearing and the r0- tatable sleeve is effected. Thus by way ofillustration, in Fig. 3 the use of the key 9 may be dispensed with bymaking the periphery of the bearing 5 with recesses 10 parallel to itsaxis, into which fit corre spondingly formed ribs or projections 11 inthe eccentric seat (3. In either case the result is the same in thatwhile the bearing is made to rotate positively with the sleeve 7, italso conforms instantly to any tendency to variations in thelongitudinal axis of the shaft A, thereby obviating undue lateral strainon the parts.

The driving gear 8 is rotated by means of the pinion 79, upon the powershaft 1 and the apparatus is provided with the usual dust guards, &c.

The sleeve 7, is made in two or more parts to admit of the placing ofthe bearing 5 within the eccentric seat 6, the said parts of the sleeve7 and the driving gear being rigidly secured together.

Having thus clearly differentiated my present structure from thatdisclosed in my concurrent application hereinbefore men tioned, what Iclaim as my invention and desire to secure by Letters Patent is,

In crushing mechanism of the character designated, the combination ofa gymtory shaft, means for supporting the same, a sleeve, a bearing forthe lower portion of said shaft seated eccentrically in said sleeve,means which insure the positive rotation of the bearing with the sleevewhile permitting the bearing to adapt itself axially to the inclinationof the shaft, and means for rotating the sleeve and eccentric.

2. In crushing mechanism of the character designated, the combination ofa gyratory shaft, means for supporting said shaft and adjusting it onits longitudinal axis, a sleeve, a bearing for the lower portion of saidshaft seated eccentrically in said sleeve, means which insure thepositive rotation of the bearing with the sleeve while permitting thebearing to adapt itself axially to the in clination of the shaft, andmeans for rotat ing the sleeve and eccentric.
